Environmental Transport Processes: Velocity Profiles and Turbulence

Understanding how fluids transport substances through natural and built environments is critical for addressing water quality, pollutant dispersion, and atmospheric flow. This text-based course guides you through the fundamental physics and practical calculations of environmental fluid mechanics. You will transition from basic fluid concepts to confidently analyzing velocity distributions and turbulent mixing in rivers, estuaries, and the atmosphere. By working through structured, step-by-step written examples, you will learn how to apply conservation laws and transport equations to real-world environmental scenarios. What you'll learn: 1. Understand the core principles of advection, diffusion, and dispersion in environmental systems. 2. Analyze velocity profiles under laminar and turbulent flow conditions. 3. Calculate turbulent shear stresses and mixing coefficients using standard engineering formulas. 4. Solve transport equations for pollutant concentration distributions in open channels. 5. Apply modern environmental modeling principles to predict contaminant transport. 6. Evaluate boundary layer dynamics in natural water bodies and the lower atmosphere. The course begins with essential fluid mechanics terminology and foundational definitions before moving into detailed derivations of velocity profiles and turbulence models. You will then progress to practical problem-solving guides that demonstrate how to calculate transport rates and mixing behaviors step-by-step. This course is designed for beginners in civil engineering, environmental science, or fluid mechanics who want to build their analytical skills. No advanced background in fluid dynamics is required.
